General Terms and Conditions
As of: September 2026
1. Scope
1.1 These General Terms and Conditions (GTC) apply to all offers, contracts, deliveries and other services of Involtis CS Photovoltaics GmbH (hereinafter “Involtis” or “we”) to its customers (hereinafter “Customer”), even if they are not specifically referred to in an individual case. In the version valid at the time the contract is concluded, they also apply to all future transactions with the Customer.
1.2 Involtis is a purely B2B trading company. Our offers are directed exclusively at businesses within the meaning of § 1 UGB (in particular installation companies, specialist dealers and assembly companies). We do not conclude consumer transactions within the meaning of the Consumer Protection Act (KSchG). By placing an order, the Customer confirms that it is acting as a business; we are entitled to request proof (e.g. VAT ID number, extract from the commercial or trade register).
1.3 Deviating, conflicting or supplementary terms and conditions of the Customer do not become part of the contract unless we expressly agree to their validity in writing. This also applies if we deliver in the knowledge of such terms.

3. Offers and conclusion of contract
3.1 The presentation of products on our website, in catalogues, presentations and datasheets is non-binding and does not constitute an offer in the legal sense. Technical information is based on the manufacturers’ documentation; changes by the manufacturers are reserved.
3.2 Our offers are subject to change unless they are expressly designated as binding. Orders placed by the Customer are binding on the Customer.
3.3 A contract is only concluded upon our written order confirmation (including by email) or upon delivery of the goods. Side agreements, amendments and additions must be made in writing to be effective; this also applies to any waiver of this written form requirement.
4. Prices
4.1 Prices and dealer terms are available on request. The prices stated in the respective offer or order confirmation are authoritative.
4.2 All prices are in euros, net plus statutory VAT, ex warehouse and, unless otherwise agreed, excluding packaging, shipping, transport insurance and any disposal or take-back fees.
5. Delivery and transfer of risk
5.1 Delivery is made, as agreed, by collection from the warehouse or by shipment to the delivery address specified by the Customer. Stated delivery dates and delivery periods are non-binding unless expressly agreed as binding. Partial deliveries are permitted insofar as they are reasonable for the Customer.
5.2 The risk of accidental loss and accidental deterioration of the goods passes to the Customer upon handover to the Customer in the case of collection, and upon handover to the carrier, forwarder or other person designated to carry out the shipment in the case of dispatch. This also applies if we bear the shipping costs.
5.3 Delivery delays due to force majeure or other circumstances for which we are not responsible (e.g. supply or transport disruptions at manufacturers and upstream suppliers) extend the delivery period appropriately. If such an impediment lasts longer than three months, both parties are entitled to withdraw from the contract with regard to the affected services.
5.4 Upon receipt, the Customer must inspect the goods for externally visible transport damage, note any such damage on the delivery note or consignment note and notify us in writing without delay.
6. Retention of title
6.1 The goods delivered remain our property until all claims arising from the respective contract, including interest and costs, have been paid in full (reserved goods).
6.2 The Customer is entitled to resell or install the reserved goods in the ordinary course of business. The Customer hereby assigns to us all claims in the amount of the invoice value that accrue to it against its customers from the resale or installation, and must record this assignment in its books. Pledging or transferring the reserved goods by way of security is not permitted.
6.3 The Customer must inform us without delay of any third-party access to the reserved goods (e.g. seizures).
7. Payment and default of payment
7.1 Unless otherwise agreed, invoices are payable without deduction within the period stated on the invoice. Payment is made exclusively by SEPA bank transfer. We are entitled to make deliveries conditional on advance payment.
7.2 In the event of default of payment, we are entitled to charge default interest of 9.2 percentage points above the base rate pursuant to § 456 UGB and the lump sum pursuant to § 458 UGB. In addition, the Customer must reimburse the reminder and collection costs necessary for appropriate legal action.
7.3 In the event of default of payment, we are entitled to withhold outstanding deliveries or to carry them out only against advance payment and, after setting a reasonable grace period, to withdraw from the contract.
7.4 Set-off against counterclaims and the withholding of payments are only permitted with claims acknowledged by us or established by a court.
8. Statutory warranty and notification of defects
8.1 The statutory warranty provisions of §§ 922 et seq. ABGB apply, subject to the following provisions.
8.2 The Customer must inspect the goods without delay after delivery in accordance with § 377 UGB. Defects must be notified in writing without delay, but no later than 7 days after delivery (hidden defects within 7 days of their discovery), with a precise description of the defect (including serial number, if available). If timely notification of defects is not made, claims under warranty, for damages due to the defect itself and arising from an error regarding the absence of defects are excluded.
8.3 The presumption of defectiveness pursuant to § 924 ABGB is excluded; the Customer must prove that the defect existed at the time of handover.
8.4 In the case of justified notifications of defects, we provide warranty at our discretion by rectification (repair) or replacement. Only if both are impossible, fail or would involve disproportionate effort may the Customer demand a price reduction or – in the case of defects that are not merely minor – rescission of the contract.
8.5 There is no warranty for defects attributable to improper storage, installation or commissioning, failure to observe the manufacturers’ installation and operating instructions, combination with non-approved components, third-party interference, natural wear and tear or external influences. The products must be installed by an authorised specialist company.
9. Manufacturer guarantees
Manufacturer guarantees (in particular Deye and Easyway Energy) are governed exclusively by the respective manufacturer’s guarantee conditions and exist independently of the statutory warranty. They do not constitute a guarantee of Involtis’ own. We support our customers in handling guarantee claims with the manufacturer.
10. Liability
10.1 We are only liable for damage in the event of intent or gross negligence. Liability for slight negligence is excluded. This exclusion of liability does not apply to personal injury.
10.2 To the extent permitted by law, liability for consequential damage, indirect damage, loss of profit, loss of production, loss of yield from PV systems, loss of data and damage arising from third-party claims is excluded.
10.3 To the extent permitted by law, claims for damages become time-barred within six months of knowledge of the damage and the party causing it.
11. Product liability
Recourse claims within the meaning of § 12 Product Liability Act (PHG) are excluded unless the party entitled to recourse proves that the defect was caused within our sphere and was due to at least gross negligence. The Customer undertakes to pass this provision on to its customers (if they are businesses). The mandatory provisions of the PHG remain unaffected.
12. Data protection
Information on the processing of personal data can be found in our privacy policy.
13. Place of jurisdiction and applicable law
13.1 The place of performance is the registered office of Involtis in 8413 Ragnitz.
13.2 The court having subject-matter jurisdiction for the registered office of Involtis (8413 Ragnitz) has exclusive jurisdiction for all disputes arising from or in connection with contracts based on these GTC. However, we are also entitled to sue the Customer at its general place of jurisdiction.
13.3 Austrian law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG) and the conflict-of-law rules of private international law.
14. Final provisions
Should individual provisions of these GTC be or become invalid or unenforceable, the validity of the remaining provisions shall remain unaffected. The invalid provision shall be replaced by a valid provision that comes closest to the economic purpose of the invalid provision.
